8-Port SAS/SATA 1.5G/3G/6G Protocol I/O Controller

The PM80 is a highly-integrated eight-port SAS/SATA 1.5G/3G/6G Protocol Controller optimized for fabric-attached RAID storage system applications and native SAS/SATA HBA applications. This cost effective solution significantly increases total system performance, diagnostics, scalability, and manageability. The PM80 provides an efficient and scalable architecture that eliminates the system performance limitations of competing SAS controller devices. It provides a application-programming interface that is compatible with Tachyon Fiber Channel controllers. The PM80 provides system designers with end-to-end diagnostics and error handling mechanisms that increases system availability and manageability. Advanced end-to-end diagnostics can be achieved from host-to-hard disk drive by using the PM80 in combination with leading maxSAS family of SAS expanders, SATA AAMUXs, and Enclosure Management solutions.

• Minimal host CPU dependency boosts overall system performance
• On-chip shared memory enables increased throughput and IOs per second (IOPS)
• Initiator and target mode support for host-to-host transactions and failover
• Hardware assist support for error recovery
